A wrestling manual from 1659.
https://www.thearma.org/Manuals/Passchen/Passchen.htm German wrestling, known as "Ringen" Especially interesting to note is the subdividing of the body in weak/half/strong parts and leveraging these to counter holds. ex: "When you try to break free from a hold, you must usually apply the Half-Strong of your arm to the Weak of your Adversarii." Also of note is that unlike many modern grappling styles, striking is allowed (this is not the case in modern versions of this, as practiced by HEMA practicioners), as are stomps (nr 38) and throat crushes (nr 37). At the end there is an explanation about how to do a double leg takedown, but this is quite different from the one we are used to, as in our modern martial arts we are more likely to "run through" the adversary, as to get him on his back, but here (probably due to the rules) they actually do more of a suplex type takedown with it, by tossing them over their head.
